Fix tests on FreeBSD

Adjust tests that relied on behavior that changed on FreeBSD:
- lstat_stat_variation18/19/20: rdev is reported as -1 (NODEV), so use
  %i instead of %d.
- socket_tcp_congestion: set the currently active congestion algorithm
  instead of hard-coding newreno, which is no longer loaded by default.
- socket_sentto_recvfrom_unix: don't expect a warning for an AF_UNIX
  datagram socket with an explicit protocol.
- setlocale_variation2: skip, as locale -a lists locales that cannot be set.
